CORPORATION or MASSACHUSETTS Applicatien fi1ede-T1ilye30, This invention relates to in'iprov-elnents in oilburners of the type in which a wick is mounted in a grooveor channelinto which the oil is fed. The so-ca1led stove or range burner er the perforated combustion tube type willserve as an exampleof one type of burner forwhich the invention is suitable; The object of the invention is to provide improved means for supporting the wick in the oil groove of the burner in a mannersuch asto maintain the loweredge of the wick The invention ofl'ers a very simpleand inexpensive form of clip. for the above purpose. A number offthese clips are pressed into the fuel groove ofthe burner at spaced 1 points throughout its length and afford saddle-like seats on which the wick rests. The inventionhas the advantage that theclips are readily applied to and removed from the burner and can be used with various kinds of wicksiwhether of ,thecorrugated form or -,The invention willbe disclosed with reference to the accompanying drawing,inwhich:

Fig. 1 is a plan view of the burner base; {Fig 2 is asectionalelevational view of a burner taken on the line 2-2 of Fig. .1, hav-J ing aplied thereto the Wick supporting means of my invention; and n 1 n Fig. 3 is a perspective view. of one of the wick supporting clips. 3

Referring tothe drawing; there is shown inFig. 2a burner of the perforated combustion tube type for the purpose of illustrating one type of burner for which the invention is adapted. However, the invention is equally applicable to any other formof burner having a fuel groove in which a wick, extending lengthwise of the groove, is to be supported in spaced relationfrom the bottom of such groove.

The burner comprises a base 10,having one or more oil grooves 11 therein, and a pair of perforated combustion tubes 12 for each groove. Such tubes are mounted one on each side Wall of each of the grooves 11 and extend upwardly therefrom to form annular combustion chambers 13, each in overlying relation with a groove 11. The base 10 has Oil is supplied toone of on. BURNER:

a central air passage 14 and, where there are two grooves, arcuate air passages 15 (Fig,

1) are provided between thesegrooves. The

grooves 11 are interconnected by radial passages 16iformed in arms 17 which intercom nect adjacent side walls of adjacent grooves.

these passages by a y A cover 19 caps the several tubes and has outlets 20 foreach combustion chamber 13. This cover blocksbfi' the upper end of the central air passage within pipe 18 (Fig. 2).

the inner sleeve as well as the upper end of the annular air passage between the two ins. termediate sleeves. y

Ineachgroovea wick such as 21 is mount- As: indicatedjby the dot-dash lines in Fig. 1,,these \vicks are of endless form and. theyare preferably corrugated throughout their length as indicated by the small portion shown in full lines. For supporting each wick in its groove a number of clips. each of the type shown in Fig. 3,, are used,these. clips beingapplied at spaced points along the Each clip consists of a short strip ofsheet metal, preferably heat resisting steel,bent into theform shown, This clip has two straight. arms 22 interconnected at their lower endsjby acurved portion 23. The arms 2-2 diverge upwardly from the portion 23and one of. them preferably extends above the other for a purpose to be later described.

This upward extension, marked 24, is prefer ably vertically disposed. j i

It will benotcd that the side walls of each fuel groove 11 converge in a downward direc: tion. The side arms 22 of the clip have the same slope and converge in the same direction and to the same degree as said walls. The

length of the arms 22 is, however, less than the height of the groove. The curved part 23 spaces the arms apart sufficiently so that the clip cannotjbe pressed all the way down in groove 11. It can enter the ,grooveuntil the upper ends of the arms 22 lie substantially flush with the upperedges of the side walls of thegroove. When pressed inthis far, the clip istightly wedgedin place between the sidewalls of groove 11 and frictionally bound thereto with the portion23 lying above the 1 2&ggroove. Consequently, simply by pressing.

2 fi f.1llll0h time may be saved in assembling the bottom of the groove and affording a saddle like seat on which the wick rests. The two arms 22 being closely spaced near their lower ends centralize the lower edge of the wick in the oil groove 1 1 Each clip, when thus positioned, has a ver tical extension 24 disposed above the top edge of the adjacent side wall of the fuel groove. When the tubes 12 are removed, these extensions 24 may readily be grasped by pliers and removed.

The clips have the obvious advantage of simplicity and low cost of manufacture. They are very easily applied to the fuel grooves and as easily removed. Even when the clips are applied by the unskilled, they are easily and properly located. The lower blunt and unspringy end 23- 'of the clip can enter only to a predetermined depth in the the clips into the groove as far as they will go, they will become properly located. The clips do not require attachment to the wick as is customarily the case. Consequently,

parts in the burner base and the work may be done by unskilled labor.

Thus, the invention affords an improved means for supporting a wick in the fuel 39 .groove of an oil, burner in such a manner that the lower edge of the wick is maintained above the bottom of the groove. This is important because the space below the wick allows for the accumulation of a considerable amount of residue before cleaning of the grooves is required. If the wicks rested on the bottoms of the grooves, they would soon become cemented thereto by the accumulation of residue. Then it would be diflicult to 4Q-eremove the wicks without distorting them or even destroying them. With the present arrangement, this does not occur and the wicks can be usedover and over again. The corrugations make the wicks stronger and better adapted to stand up under frequent handlings and have a longer useful life. Since the clips are not attached to the wick, the latter, after the upper edge has become unfit for further service, can he turned upside down .to present a fresh upper edge and secure a still further increase in the useful life of the wick.

What I claim is:

1. In an oil burner, a fuel groove having side walls which converge downwardly toward the bottom thereof, a plurality of clips pressed, into the groove between its side walls at spaced intervals throughout the length of the groove, each such clip comprising two arms and an integral connecting portion toward and to which said arms converge, said converging arms lying against and frictionally engaging the converging side walls of said groove and said connecting 6 portion being of greater width than the bottom of the groove, whereby the depth to which the clip can be pressed into the groove is limited by said portion and the latter is spaced above the bottom of the groove, and a Wick resting upon the connecting portion of said several clips and between the side walls thereof.

2. In an oil burner, a fuel groove having side walls which converge downwardly toward the bottom thereof, a plurality of clips pressed into the groove'between its sidewalls at spaced intervals throughout the length of the groove, each such clip comprising two arms and an integral connecting portion toward and to which said arms converge, said converging arms lying against and frictionally engaging the converging side walls of said groove and said connecting portion being of greater width than the bottom of the groove, whereby the depth to which the clip can be pressed into the groove is limited by said portion and the latter is spaced above the bottom of the groove, and a wick resting upon the connecting portion of said several clips and between the side walls thereof, one of said arms being long enough to extend above the top edge of the side wall with which it is engaged.

3. In an oil burner, a fuel groove, a series of roughly U-shaped spring clips pressed into said groove and having the two arms of the clip frictionally engaged with and supported by the side walls of'the groove, means on each clip to limit the depth to which it can be pressed into the groove and locating the bottom of the U-shaped clip at an elevation above the bottom of the groove, and a wick supported by said several clips between the armsof each clip with its lower edge resting upon the portion of each clip which connects said arms.

.4. In an oil burner, a fuel groove, a series of roughly U-shaped spring clips pressed into said groove and having the two arms of the clip frictionally engaged with and supported by the side walls of the groove, and a wick supported by said several clips between the arms of each clip with its lower edge resting upon. the portion of each clipwhich connects said arms.

In testimony whereof I have affixed my signature;
